Some of Norwich's most historical landmarks remain almost invisible in the hustle and bustle of our modern lives.
The church of Saint Mary the Less - also known as the "French Church" - sits wedged between two estate agents in Queen Street, with only its door and tower visible from the street.
Built in the 13th century for a rapidly growing population, the church saw continued use until 1544 when its parish was combined with the nearby Saint George in Tombland.
With the influx of Flemish refugees to the city in the 1500s, Saint Mary the Less was let to what became known as "the Strangers" to be used as a cloth hall.

The Strangers stayed in the building for nearly 70 years before French-speaking Walloons were given a 40-year lease from the city to use it as a church again, where it earned the nickname of the "French Church".
Subsequently leased to the Swedenborgians, it briefly flourished as a Protestant church before fading again in the 1800s.
Saint Mary the Less changed hands once more to the Catholic Apostolic Church and used it until 1959 when furnishers Robertson and Coleman bought it to use as a warehouse and store.

This venture closed in 1985 and the church was then sold to a private owner where it has slowly been forgotten ever since.
With its cultural significance known and management brought into question, several organisations have rallied to have it appropriately preserved, fearing it has been falling into disrepair.
Conservation group SAVE Britain's Heritage added the church to its list of "at risk" buildings several years ago, with Historic England and Norwich City Council last able to gain access in 2014.
Cathy Eden, project coordinator of The Forum's Open Heritage Days, once described it as "one of Norwich's hidden treasures".
